Line break formatting error
Please have a look at the comment (in Russian) in https://postgresqlco.nf/doc/ru/param/log_destination/
Google Translate translates it as:
error in the example of the contents of the current_logfiles file - no line break:
stderr log / postgresql.logcsvlog log / postgresql.csv
instead of
stderr log / postgresql.log
csvlog log / postgresql.csv
Please review, might be a formatting error on our side.
